Scientifically proven to shield and defend the body

In developing the Marf, we were able to transform the concept of providing a protective and valuable accessory into a product that’s scientifically proven to shield and defend the body. Our dedication to providing a safe and healthy environment starts with the Marf.

To guarantee our commitment in providing a superior and safe-to-use product, we conducted extensive testing to ensure the Marfs’ Viral Shield Technology is as beneficial as we claim it is. By conducting a variety of standardized tests that were thoroughly evaluated by an independent ISO 9001 certified facility and tested under internationally recognized ASTM (American Society for Testing and Materials) metrics.

Our belief is as simple as this:

“If we wouldn’t recommend the Marf to our family and loved ones to use, we wouldn’t recommend it to our valued customers either.”


-Edward Jones, Creator of Marfs

Bacteria Reduction

By milling the bamboo charcoal into tiny particles and melting elemental silver into our fibers we’ve created a premium and versatile fashion accessory that shields you from offending germs and disease-causing bacteria.

This test examines the Marfs capabilities to eliminate two kinds of bacteria (both of which are two of the main types of bacteria that cause infections in people with cancer- American Cancer Society):


Staphylococcus is a genus of Gram-positive bacteria. Under the microscope, they appear round, and form in grape-like clusters. The Staphylococcus genus includes at least 40 species. Of these, nine have two subspecies and one has three subspecies. Visit the CDC for more info.


Klebsiella is a genus of non-motile, Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. It is named after the German microbiologist Edwin Klebs. Klebsiella species are ubiquitous in nature. Visit the CDC for more info

The tests were conducted by measuring the concentration of seeding bacteria that latched onto the surface of the Marf versus the surface of a regular scarf. Bacteria levels were recorded before and after washing both variables.

Before being washed:

  • Marfs showed a DECREASE in bacteria levels for Staphylococcus and Klebsiella by 72% and 61%, respectively.
  • The regular scarf showed a 20% INCREASE in Staphylococcus level and a 19% INCREASE in Klebsiella levels.

Bacteria Reduction Results
Test Items Before Washed After Washed
Staphylococcus Concentration of Seeding Bacteria (cells/ml) 5 5
Control 5.99 3.60
Marfs 2.91 0.54
Klebsiella Concentration of Seeding Bacteria (cells/ml) 5 5
Control 5.95 3.15
Marfs 3.11 0.28

After being washed:

  • Marfs capability to decrease Staphylococcus bacteria levels was TWICE the amount of a regular scarf.
  • Similarly, the Marf showed a 91% decrease in Klebsiella bacteria levels after being washed, versus a 47% decrease for a regular scarf.

ASTM F 1862- Bodily Fluids Resistance

Background: ASTM F 1862 is a standardized test method that was conducted to evaluate the resistance of Marfs to a fixed amount of bodily fluids at a high velocity, and is a pass/fail determination based on the penetration or not of the bodily fluid.


Marfs have demonstrated to provide an adequate amount of protection against the spread and transfer of bodily fluids. Marfs can be used to help prevent the spread of infectious diseases. View the Marfs Certification of Approval.

Far-Infrared Testing (FIR)

Far Infrared Rays are an extremely beneficial form of energy, which occur naturally. Through our unique design, the Marfs fibers are capable of emitting the same wavelengths as FIR energy from the sun. The results below illustrate the Marfs ability to produce the same benefits of FIR and its absorbing properties, as opposed to any regular scarf.

You may be asking yourself, “So, how does this benefit me?”

Here are some of the health benefits associated with FIR energy:

  • Increases blood circulation and oxygen levels
  • Increases energy levels
  • Improves muscle strength and tone
  • Optimizes lymphatic flow to reduce inflammation
  • Increasing immune system response time to strengthen white blood cells
  • Increases metabolic rate
  • Releases toxins in the body
  • Rejuvenates the biological function of cells and autonomic functions of our nervous system
